Colombia (/kəˈlʌmbiə/ ), officially the Republic of Colombia,[Note 1] is a country largely situated in the north of South America, with land and territories in North America. Colombia is bounded on the north by the Caribbean Sea, the northwest by Panama, the south by both Ecuador and Peru, the east by Venezuela, the southeast by Brazil, and the west by the Pacific. It comprises thirty-two departments, with the capital in Bogotá. Colombia is ethnically and linguistically diverse, with its rich cultural heritage reflecting influences by various Amerindian civilizations, European settlement, forced African labor, and immigration from Europe and the greater Middle East. Urban centres are concentrated in the Andean highlands and the Caribbean coast.
